If anything, I think its odd to post over 100 photos of someone else's wedding to one's own FB page.
What sort of photo limit would you consider more reasonable?
Granted my wedding occurred before Facebook, but even as the Bride I would never have posted 100 photos.
I think the Bride feels that her thunder was stolen.
Most brides spend lots of money to get their hair and make-up done. They spend considerable time picking a dress, ect. Their wedding portrait is what they want to be their official photo. They don't want a pic where they have a goofy look, or where they are taking a bite or whatever.
Then honestly, they should get over themselves. I have tons of photos from my wedding where I'm eating, or in the middle of talking, or whatever.
If I don't like a photo of myself, I untag it and move on. It's totally delusional to think that EVERYBODY who knows you doesn't know what you look like already. I could post some really nice photos of me with lovely hair and makeup, smiling prettily. And all my friends would think, "What a lovely photo of Teenyweeny". They wouldn't suddenly think I was prettier than I actually am. They know what I look like, for pete's sake!
Or, they might see a photo of me squinting, with ruffled hair, and a mouthful of food. I doubt they're suddenly going to say, "Oh, actually, she's a total hag! I can't believe I never noticed it before!"
If anybody seriously gets offended by 'too many photos', or feels that their 'thunder was stolen', then they need to get over it. Your wedding is A DAY. A magical, wonderful, joyful day, but still A DAY. You can't milk it for weeks afterwards, obsessively controlling the 'image' of your 'perfect day'.
Nobody else cares about your wedding as much as you do. They might care about YOU and your partner, and your marriage, but to them your WEDDING was one special day that they got to share with you. Don't let other people's perception of it take up so much space in your head. It almost certainly isn't taking up any space in theirs.
